[libcamera-devel] [PATCH v2] gstreamer: Fix unused variable error

[Laurent Pinchart]

From: Jaslo Ziska <jaslo at ziska.de>

Commit fd84180d7a09 ("gstreamer: Implement element EOS handling") has
introduced a compilation warning with clang:

../../src/gstreamer/gstlibcamerasrc.cpp:768:23: error: unused variable 'oldEvent' [-Werror,-Wunused-variable]
                g_autoptr(GstEvent) oldEvent = self->pending_eos.exchange(event);
                                    ^

This seems to be a false positive, but nonetheless breaks the build. Fix
it.
